The National Aeronautics and Space Administration (NASA)'s Hubble Space Telescope ejected measurements validate that the Universe is expanding about 9% faster than expected based on its trajectory seen shortly after the big bang. It was published in Astrophysical Journal Letters on April 25.The researchers using Hubble as a "point-and-shoot" camera to look at groups of Cepheids using a new method called DASH (Drift And Shift), while Hubble can observe one star for every 90-minute orbit around Earth.Adam Riess, Bloomberg Distinguished Professor of Physics and Astronomy at The Johns Hopkins University, Nobel Laureate and the project's leader,is the first author of the research.

The International Hockey Federation (FIH) has imposed a fine of 170,000 Euros on Pakistan Hockey Federation (PHF) for not honouring the Pro League commitments and has given PHF a time-limit till 20th June, on failure of which PHF would have to pay double of penalty.The PHF was fined because it did not send the national team for the Pro League matches in Argentina, Australia and New Zealand.Shahbaz notified that since PHF lacks funds, the FIH has been requested to reduce the fine and allow it to be paid in instalments. PHF Secretary General Shahbaz Ahmed is a former Olympian and captain of Pakistan National Hockey Team and is a member of the FIH Executive Board, chaired by India's Narinder Batra.

The Indian Embassy in Abu Dhabi and the Indian Consulate in Dubai have issued cautionary warning to the Indians seeking jobs in the UAE, saying that they must authenticate their employment offers and permit visas before arriving in the country.

R K Singh, Minister of State (IC) for Power and New & Renewable Energy released a book on "Weather Information Portal for Indian Power System"s, at Power System Operation Corporation limited (POSOCO), New Delhi. This book is a reference document developed by POSOCO along with IMD (India Meteorological Department) to enable better usage of Weather Portal in all areas of Power Sector. POSOCO manages the Inter-State Transmission of Power to utilities throughout India.

SpaceX launched the U.S. Air Force's newest 'GPS III' satellite on a Falcon 9 rocket from Cape Canaveral Air Force Station in Florida, USA. The solar-powered spacecraft, dubbed "Vespucci," is the company's first official "National Security Space" mission. Vespucci's nickname honours Italian cartographer and explorer Amerigo Vespucci, after whom North and South America were named. It was competed through the Air Force's Evolved Expendable Launch Vehicle program. The successful GPS III SV01 mission marked SpaceX's 21st and final launch of 2018, beating the company's 2017 flight rate of 18 launches.

The National Panchayati Raj Day is celebrated every year in India on 24th April. The Constitution of India recognizes Panchayats as 'Institutions of self-government'. This day marks the passing of Constitution (73rd Amendment) Act, 1992 that came into force with effect from 24 April 1993. The Amendment Act permits states to take steps to organize village panchayats and provide them with necessary powers and authority necessary to facilitate them to function as units of self-government. The first National Panchayati Raj Day was celebrated in 2010. The enactment of the 73rd Amendment Act had led a defining moment in the history of India which helped in the decentralization of political power to the grassroots level. In turn, it had led to the institutionalization of Panchayati Raj (PR) through the village, Intermediate and District level Panchayats.

Scientists from Ulsan National Institute of Science and Technology (UNIST) in South Korea have developed a system that can produce electricity and hydrogen fuel from carbon dioxide. The Hybrid Na-CO2 system can continuously produce electrical energy and hydrogen through efficient carbon dioxide (CO2) conversion with stable operation for over 1,000 hours. The key to this technology is the easy conversion of chemically stable CO2 molecules to other materials. Much of human CO2 emissions are absorbed by the ocean and turned into acidity. The researchers focused on this phenomenon and came up with the idea of melting CO2 into water to induce an electrochemical reaction.If acidity increases, the number of protons increases, which in turn increases the power to attract electrons. If a battery system is created based on this phenomenon, electricity can be produced by removing CO2. In particular, this system has shown stability to the point of operating for more than 1,000 hours without damage to electrodes. The system can be applied to remove CO2 by inducing voluntary chemical reactions.

Google launched a new search engine called 'Dataset Search', which works in multiple languages, to help scientists, data journalists and others find data required for their work. The new search engine will work like Google Scholar, the company's popular search engine for academic studies and reports.
